Step 418, otherwise it is transferred to step 416.
Step 416, cover processing is carried out to pseudo random number.
In the present embodiment, by taking above-mentioned pseudo random number 101 as an example, it is assumed that character digit needed for password-type is 4, then exists
One 0 is supplemented before pseudo random number 101, obtaining final pseudo random number is 0101.
Step 418, pseudo random number is converted according to code book, obtains password.
In the present embodiment, corresponding plaintext character in pseudo random number and the character combination side are included in each code book
Mapping relations in formula between corresponding ciphertext character.Such as when pseudo random number is 0101, it is assumed that character combination mode is " to receive
Tail be number, remaining be letter ", then the pseudo random number 0101 at least corresponds to two code books, and " number is included in a code book
The mapping relations of word (plaintext) → number (ciphertext) " include " digital (plaintext) → letter (ciphertext) " in another code book
Mapping relations；As an exemplary embodiment, table 1 shows " digital (plaintext) → digital (ciphertext) " of an exemplary embodiment
Code book, table 2 show " digital (plaintext) → alphabetical (ciphertext) " code book of an exemplary embodiment, then pseudo random number 0101
9y9y can be correspondingly converted to.
